Great points.

Regular solar cells with better efficiency are already are thing, even in a compact travel format or as a novelty part of some electric cars. Those are cheap to produce, but still aren’t practical at all, unless we’re talking about something like a 2m² solar panel to charge a phone in a somewhat reasonable time on a very sunny day in an off-grid situation.

Using transparent solar cells additionally to regular ones in buildings instead of windows is pretty much the only reasonable application I can think of right now, but with a visible transmittance of 20% that’s kinda farfetched as well.

I wrote a simple, locally running Webapp some time ago, that targets the Lemmy Import-/Export-API and supports transferring only specific userdata between accounts, as demonstrated in this corresponding Wiki Entry.

The import functionality in Lemmy is additive in nature, meaning anything you import gets added on top of existing settings instead of replacing it.

Does the same thing as these manual instructions for this usecase, may be helpful to some.
